^ To all whom t may eminem chines and more particularly tothe tabulatormechanism of such machines.

ill/ly invention has for itsprincipal object to provide improved meansfor setting and restoring the tabulator or column stops and especially,for and restoring said stops by meansof keys in the keyboard of 'themachine.

-The key operated restoring or clearing means whichA I have provided, iscapable ofV clearing the tabnlator entirely, that is to say, restoringall of the set tabulator stops', and it is also capable of restoring anyselected set stop. l p

My stop set mechanism is simple in construction snd is readily adaptableto eXisting machines, or to certain existing machines, by utilizing aspart of the'mechanism features already present in said ma.- chines. I

To the above and other ends which will hereinafter appear, my inventionconsists in certain features of construction` and combinations andarrangements of parts, all of which will be fully set forth herein andparticularly pointed out in the claims.

In the drawings, parts have been broken away or shown in section, oromitted en-V tirely, as has been found convenient.

x I have shown my invention applied to a Smith Premier No. l0typewriter. The main. frame of this machine comprises side platesPatented Mar.. di, i917). i

1l which include posts l2 and on which is supported the top plate 13.Said side plates are connected together by said top plate,

by a back frame bar 14, a keyboard plate 15, a front plate 1G, and otherparts. Standards li' rising from the top plate 13, support a stationarycarriage rail 18 on which a carriage 20 is adapted to travel through theusual ball hearing connection. riage has the usual platen frame. 2lmounted therein and in which the platen 22 is mounted. 'The carriage isfed' toward the left by means of a spring 9.3 coiled Vin al drum 24. andsaid spring is connected with u large gear wheel 25 which meshes with arack 26 on the carriage. Another large gear wheel 27 meshes with saidrack and both the gear wheels 27 and 25 and the spring` drum 2i have anarbor 2S. -The gear Q7 meshes with a" pinion 30 formed as shown .in Fig.l with ratchet clutchv teeth on'its rear face, .and said clutchteethintermeshv Said carwith similar teeth on a splined clutch memher 3lwhich is pressed by alight spring toward the clutch pinion 30. Theclutch member 3l is splined on a shaft 33, which lshaft drivestheescapement wheel of the ward end ina frame plate (not shown) and at itsrear end on a pivot screw 34 threaded through an ear oi a frame plate 35constituting 'part of the casing which carries the carriage driving andescapement mechanism. The clutch member 31 ris adapted to he movedtoward the rear of the machin4 away from the clutch member 30 by meansof a rocking member 3G pivoted at 37 and 3d in ears of the plate 55.Said rocking member 36 has at its upper end `a roller 40 that bearsagainst a bar 41 constituting` part of a bail having` arms 4i) pivotedto the car- 'ringe at 42% and constitutingpart of the ordinary carriagerelease mechanism of the. Smith ,Premier machine. llach'ot' the arms 42has a forwardly extending' arm, not here shown, but having a key on itsforward end; and theconstruction is such that when said key is depressedthe bar 41 is moved toward the rear of the machine, the member 3G'isrocked about its pivots, and the clutch memn ber` 31 ismoved to its flisconnecting` position.

The machine is Iequipped with various paper feed devices not necessaryhere to bc described but comprising paper lingers 44, Fig. 5, and apaper table 45.

The machine also comprises margin stop -and line lock mechanismincluding a toothed shown in the drawings are like, and they may, itdesired, he identical with, parts heretofore commonly used in the SmithSaid mechanism inmachine shown in the drawings being equipped with aseries ot denominational stop bars 52'extending up at the back ot' themachine at their upper ends, and at their lower ends extending; down infront of the back plate or bar 14. Said stop bars are pivoted at 53 'toa. series of nested hails, each comprising an arm 54, a cross-bar 55 andanother arm 56. The arms 54 and 56 are pivoted onal horizontal rod 57mounted in a frame 5 8 which is secured, as hy screws 60, 'tothe-backbar 14. Each of they arms 56 is formed or provided with a dependingbranch 61 to which ispivoted the rear end of a long push rod 62, whichat its forward end carries a key/63. Said keys pass through a guideplate 64 which is suitably mounted on the fronthar 16 and has anindicating i. ,erases vatcd. 1t will be perceived that the nested hailsserve to reverse the order of the tabulator keys as compared with thatof the tabulator stops. vlllithout this reversal of order, the l'ceys atthe front of the machine would be. arranged in the reverse et theirnatural order, as they are in many denominational tahulators. it willalso' be perceived that each of said hails is in eli'ect hell-crankhavingr a depending arm (S1 connected with a push rod (i2 and arearwardly extending armto which a stop har is lpi voted.

in order to operate the carriage release, each of the arms 5G isprolonged toward the rear of the machine as shown, and a umy vcrsal barlies over the rear ends o these prolongations in such position that itwill be moved upward whenever one of the taba# lator keys is operated.Ars here shown, s: universal har consists of a plate of she metalhaving' its for ard edge bent down to overlie the arms 56 and said platesecured as by screws 7l to a huh or arm 7i). rigidly mounted on a, rockshaft 73, which rock shaft is journaled in ears 74 of the frame bar 14.Said huh or arm 72 is shown formed with a depending arm 75 with anvadjustable stop screw 76 mounted therein,

for contacting with the frame har 14 to limit the downward motion of theuniversal bar. Said universal. bar is moved downward hy means ot acompression spring 7.7', Fig. 1, coiled about a post 78 depending;- fromthe frame har 14` The carriage release mechanism connected with theuniversal baril), comprises a lever 80 pivoted at 81 to an ear 82 of theframe plate 14 and at its upper end lyingr in front of the carriagerelease device 36 hereinhefore described, so that, if `the upper end ofthe lever 80 he rocked toward thev rear of the machine the clutch 31will be opened.

vThis lever in the Smith Premier machine is connected with the universalbar throughl the instrumentality of a second lever S3 piv oted at 84 tothe side of the lever 80 andhav* ing a forked lower end which straddiesa pin S5, Figs. 5 and 6, projecting from an arm 86 mounted onthe rockshaft/73. The

` lever 83 is normally prevented/'from turn ing about its pivot 84 bymeans oi a pin or rod 87 which projects through a hole in the lever 80and has its end/.lying 1n the path ner/'gees g:

vescapement, notwithstanding' the tabula-tor` key is still held in itsoperated position.

Said rod is pulled toward the right in'the Stops are set by operation ofreuerse tabulating, as will be described hereinafter.

Thereturn motion of the keys under the impulse of their springs 00, islimited by a cross bar 88,1? igs. 1 and 0, mounted on the underside ofthe lframe 58 by means of screws 90 passingvthrough slots to allowadjustment of saidl cross bar 88.

'.lfhe column stops 91 are mounted on a square bar 92 having in itsupper and under sides slots a letter space distance apart after theordinary fashion of column stop bars. and said bar is squipped with afull set o1' column stops one for each letter space position. The bar 92is secured by screws 921 to the under ends of arms 91 which at theirupper ends are loosely mounted on the rock shaft vle hereinbe'loredescribed as sup` porting the margin stop bar 16, which bar 10, it willbe recalled, can `beiturned to the position shown ,in dotted lines inFig. 1 .for the purpose of setting the margin stops. In the omithPremier No. 10 machine as heretofore constructed the column stop bar.

rould be turned up together to a position convenient for setting thestops. 1n the present case, hor. er, the tabulati-)r column keys in thekeyboard and the column stop har is therefore removed` from theswinging` frame and is mounted on the separate arms 91. These arms arerendered incapable of :nvinging and at the same time are reiidcredadjustable in a front and bark direction oy mountingl themI looselyinstead ot rigidly on the shaft 48 and by providing' each ol' them withtwo adjusting screws 95. iin. the first threaded` through the arm 91-and bearing against the carriage rail at the back, and the secondthreaded through a horizontal branch 97, Fig. 1, of the arm 911 andbearing,r against the upper surface of the carriage rail. loosening oneot' these screws and tightening the other the bar 92 can be adjustedfront orback, and when both screws are tight the bar is held againstfront and back motion. rEhe screws 95 and 90 can. be provided with locknuts 1n order to provide for a line adjustment the machine.

-110 by a pivot screw 111.

of the bar 92 lengthwise, the screws 93 can be made to pass throughslots 1n sald bar 92 and one end of said bar 92 bears againstA the headof a screw 100, Fig. 5, which 'screw is threaded into the enlarged lowerend of the arm 9i.. The bar vis adjusted with precision by the screw 100after which the screws 93 are tightened. lf at any time it is necessaryto remove the bar 92 it can be replaced with' precision by merelypushingit up against the screw 100 before tightening the screws 93.

The upper ends of the denominational stops 52 are guided in ai' suitablyslotted plate. 101 mounted onthe upper, end of a. frame 102. -which/ispivoted on a rod 103, Fig. 7. in a bracket 1045 which depends from thetop plate 13 to' which, as here shown, it is secured by screws 105. Inthe Smith Premier machine as heretofore manufactured. the frame 102 ispivoted in this manner in order to secure a column Iinmpv ing,` orcolumn selecting feature, all as fully dated Jan. 24, 1910.

The 'pivot/ed frame 102, both in the pres ent construction and also inthe ordinary Smith Premier machine, is controlled in its pivotalmovement by an arm 106 -forming part of said frame and extending'downward below the pivot rod 103 into the base of 1 connectza link 107to the lower end of said arm by a pivot 108, and said link extendstoward the front of the machine beneath the keyboard, its forwardendbeing pivoted to a three-armed lever The link 107 is pivoted to adownwardly extending arm of lever 110, and said lever also has aforwardly extending arm to which is pivoted the stem 112 of a stop setkey 113. Said lever also has a rearwardly extending arm to which ispivoted the stem 11sl of a clear7 key 115. The lever 11() is pivoted at110 to a plate 117 which is secured. as by screws 118, to one of theside plates 11. A yielding' detent 120 is' pivoted to the plate 117 at121` and it has a spring 122 connected'therewith and pulling'the forwardend oi' said detent downward. At its Jforward end said detent has aroller 123 which engages a notch or depression in the center of theupper surface of the lever and holds said lever in its normal middleposition shown inl Fig. 1. 1f the key 115 be depressed the lever will berocked as shownin full lines in Fig. 2, the roller 123 riding` up on theforward arm of. the lever and tending to restore the lever to normalposition. It' the keyf113 be depressed the lever will be rocked in theopposite direction as shown by broken lines in F 2, and .then said keyis released'the parts will be restored to their normal, middle positionby the detent. I f

lVhen the key 113 is depressed the link :namens end said wiper. ismounted on a separately' pivoted frame or arm 134, the wiper itselfbeing directly1 mounted on a plate 135 (Fig. 8) which plate is securedby screws 136 to said arm 134. Said arm `or pivoted device 184 isjournaled on a rod 137 mounted in ears 138 of the bracket 104. Thedevice 134 is held in its rear position by a plate spring 140 lsecuredby a screw 141 to the bracket 104.

In order to move the pivoted device 134 and wiper 133 toward therearwhen the key 115 is operated, a pin '142 is secured in and projectsupward from a guide arm carriage other. I

143 'consisting of a bracket on or a branch of the frame 102. Thisguidearm extends backward from said frame into av notch or space between twolugs 144 depending from the flange of the top plate 13; and said guidearm constitutes ay part ofthe ordinary Smith Premier construction. ,Itwill be perceived that when the key 115 is depressed` and the frame 102rocked toward the rear,

the pin 142'carries the wiper 133 rearward i with it as shown in Fig.12; but when said frame is swung toward the front by the key 113, thepin 142 moves away from the wiper 133 and leaves said wiper in itsnormal position, as shown in Fig. 11.

In operation it will be perceived that any column stop can be set in themannerhereinbefore described; and if then the operator perceives that hehas set vthe wrong stop he can immediately restore it by an operation ofthe key 115', after which he can move the carriage to the correctposition and set the correct stop. Also, if a number of stops have beenset and it is desired to restore any one of them independently oftherest, this can be done by oper ating the tabulator key corresponding tothe decimal point so as to bring that particular column stop intoregister with the wiper 133, and then operating the key 115. If it isdesired to restore all of the column stops, this can be done bydepressing and holdingdown the key 115 and moving the from one end ofits travel to the It wil .-'be pe ceived that this stop-set mechanismhas the advantage over most others that both the set, key and the clear:key are in the keyboard of the machine whe'rethey can be operated witha maximum of convenience and also that the entire mechanism is quitesimple and that use has been made lfor some of the operating parts, ofmechanism already in the manufactured machine so that this key settabulator can be very readily" incorporated into existing machines.Moreover, my mechanism is availablev as an alternativeconstruction sothat in the processof manufacture machines can be equipped either withythe former column-selecting tabulator'or with my stop-set tabula-tor atthe option of the purchaser.

My Amethamsm does not interfere witln other functions of the tabulator.For ex# ample, the Smith Premier tabulator as herey tofore manufacturedis adapted for reverse tabulating, that is to say, for using-thetabulator stops to arrest the carriage on the rel turn travel of saidcarriage toward the right as well as in its travel toward the left. AInthis operation it is necessary to compensate for the difference inposition of arrest of the carriage due tothe fact that when the carriageis traveling toward the left the 'column stop 91 encounters theleft-hand face of a stop whereas when the carriage is traveling towardthe right the column stop encounters the right-hand face of said stop.In the Smith Premier machine this compensation is eected by: allowingthe frame 102 to move a suitable distance to-.. ward the right inreverse tabulating". 4,To this end the rod 102 is tight'in its bearingin the bracket 104 and the two arms of the frame 102 are pivotally,mountedv on said' rod butn the spacing of said arms,.as shown@` 5 inFig. 8, is such as to Aallow the frame 102 to slide lengthwise of therod. In order to hold said frame in its normal left-had position, or inits right-hand position as seen" from the rear in Fig. 8,' part of thehub of the frame 102 is chambered out to accommodate a compressionspring 145 and thev end of the rod 104 is formed with an elongated head146; and the spring 145 is compressed between said head 146 and theshoulder formed by the bottom of the chambered out part of the hub sothat the spring tends to move the frame 102 toward the right in A` Fig.8 or toward the operators left. ,The

motion lof the frame 102 in a right andleft direction is limited-by theguide arm 143 as will be understood from Fig. 8 wheresit will be` seenthat this arm is normally pressed against the right-hand one of thelugs'144 but that there is space for it to move a little to the leftbefore it strikes the left-hand one of said lugs.

The rod 87 in the base of the machine (Figa) ispivot'ed at one end at147 to an ear 148 of the arm 106, the construction beingsuch thatwhenthe frame 102 and arm 100 are moved toward the operators right,

jthat is to say, toward the left in Fig. 5, thp

rod 87 will also be moved in the same direction and the end of said rodwill become disengaged from the lever 83, thus in eect '13' Smithiixreinier mach" bres-kin@ the lever-80 and ellowin the clutch uw I ,A sineinber lto be restored to its connection with the. clutch member TSG,theel instantly restoring the cai'rieie to t" con.'
